South of Pallet Town is Cinnabar Island. Enter the Pokémon Laboratory and get some new Pokémon. Depending on what fossil you got in Mt. Moon, you can get Kabuto or Omanyte. You can also get Aerodactyl if you picked up the Old Amber in Pewter City's museum. Three people there will trade your Raichu for an Electrode, your Venonat for a Tangela, or your Ponyta for a Seel. Non of these are too important, but they can rack up experience quickly. There is a Pokémon Mansion here with puzzles involving switches. Behind a pillar on the first level is the final piece of the Moon Stone. Read the text to find out about the mysterious Mewtwo Pokémon. Here you can get Grime, Muk, Koffing, Ponyta, Vulpix (BLUE) / Magmar (RED), etc. You will also get a key for the gym. The gym leader, a mad scientist named Blaine, uses fire Pokémon. Water works very well on them. If you win he will give you a very powerful fire attack (FIRE BLAST). Now you only have one more Gym left...
